Benefit is claimed under 35 U.S.C. 119(a)-(d) to Foreign Application Serial No. 1314/CHE/2012, filed in INDIA entitled “ARCHITECTURE FOR ENERGY MANAGEMENT OF MULTI CUSTOMER MULTI TIME ZONE DISTRIBUTED FACILITIES” by Wipro Limited, filed on Apr. 2, 2012, which is herein incorporated in its entirety by reference for all purposes.

TECHNICAL FIELD

Embodiments of the present subject matter relate to energy management. More particularly, embodiments of the present subject matter relate to energy management of multi customer multi time zone distributed facilities.

BACKGROUND

According to the international energy agency (IEA)-world energy outlook report 2010, demand for energy in the world is expected to increase drastically in coming few decades. Whereas, sources and supply of conventional energy like electricity from utility companies is going to be limited. This may lead to a huge supply-demand gap in energy. Also, the energy needs to be efficiently used to reduce carbon footprint. One of the major challenges faced by large consumers of energy, for example, a distributed facility or a process plant is to reduce energy consumption without compromising on the quality of operating conditions and quality of services. Under these circumstances environmental sustainability has been drawing a greater attention.

A plethora of advanced technologies are being implemented in order to optimize the rate of consumption of energy. For example, in geographic locations where the climate varies significantly, energy consumption control in accordance with operating conditions becomes even more relevant.

Further, regulatory policies governing energy supply & consumption also vary from country-to-country and even within a single country. Furthermore, different organizations owning the distributed facilities or process plants set forth policies related to operating conditions and energy consumptions as desired by them. The maintenance of required operating conditions in the distributed facility or process plant becomes even more complicated and challenging, with consumers opting for a combination of multiple sources of conventional and unconventional energy supply in a dynamic way. Moreover, cost and quality of energy consumed from different sources may also be significantly different can further add to the complexity to maintenance of required operating conditions.

Moreover, in any system, optimization of energy consumption and related controls is greatly influenced by granularity of measurement and metering of consumption. Since granularity and extent of metering is limited by practical constraints like constituency of metered area as recognized by the energy supplier and cost benefit analysis of own metering in the distributed facility, accurate and granular of measurement of energy consumption at an individual device level remains a myth.

In a typical distributed facility (e.g., a multi-facility), there can be different classes/types of devices performing different functions. Some of these devices directly contribute to environment control and some indirectly. Devices belonging to a device group performing same or similar functions may further have different characteristics. However, typically facility management systems implement individual level control of devices or a group of devices for such purpose. This may make the process of environment control less effective and less efficient because of lack of traceable and lesser controllability, to maintain desired operating conditions.

Existing techniques do not provide an intelligent and comprehensive energy management solutions for optimization of energy consumption and control of such complex aggregation of diverse devices in multi customer multi time zone distributed facilities, such as process plants, office spaces, retail outlets and the like for achieving desired operating conditions within the given set of policies.

The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present subject matter is defined by the appended claims.

The term “energy management” refers to service and consumption management of infrastructure associated with energy across one or more distributed facilities located in different time zones.

The present architecture allows scalability of the energy management from a decentralized energy management to centralized energy management environments.

FIG. 1 illustrates a flowchart 100 of a computer implemented method for energy management of multi customer distributed facilities located in different time zones, according to one embodiment. At block 102, associated energy models of the multi customer distributed facilities are formed based on parameters, such as facility characteristics, device characteristics, service characteristics, customer needs, available energy sources, customer policies, regulatory policies and the like using a user interface layer. The multi customer multi time zone distributed facilities are explained with reference to screens 300, 400, 500 and 600 shown in FIGS. 3, 4, 5, and 6, respectively. The outputs of energy model are explained with reference to screens 700 and 800 shown in FIGS. 7 and 8, respectively. At block 104, data associated with energy management of the multi customer distributed facilities is obtained based on the associated energy models by a data acquisition/integration layer. Exemplary data includes automated meter data, emissions data, digital invoice data, device and sensor data, enterprise resource planning (ERP) data, weather data, emergency alert data, service desk data and the like.

At block 106, the obtained data for energy management of the multi customer distributed facilities is transformed by a data management layer. In one embodiment, the obtained data is mediated by a data mediation module in the data management layer. Further, the mediated data is normalized by a data normalization module in the data management layer. Furthermore, the normalized data is validated by a data validation module in the data management layer.

At block 110, control commands are generated using the processed data and associated one or more pre-defined thresholds and set-points by the energy transaction layer. In one exemplary implementation, control commands are generated based on the processed data, associated one or more pre-defined thresholds and set-points and dynamic decisions obtained from the energy efficiency management layer by the energy transaction layer. Exemplary control commands include thermal control, consumption control, operational modes control, utilization control, demand control, eco-mode control, energy source control, carbon emission control, performance monitoring control and the like.

The commands for threshold adjustment based on operation data is explained in Appendix A. In another embodiment, the one or more predefined thresholds and set-points are updated based on an energy knowledge base in a framework and utilities layer by the energy efficiency management layer. Further, statistical and root-cause analysis is performed on the operational data by the framework and utilities layer to obtain energy optimization data upon receiving a request from the energy efficiency management layer. The statistical and root-cause analysis is explained with reference to screen 1000 shown in FIG. 10. For example, the energy optimization includes output of historical data analysis that provides deviation and information about what to optimize. The energy management information is then updated using the energy optimization data by the energy efficiency management layer. For example, energy management information includes information regarding what is to be done to optimize energy. Furthermore, control commands are generated using the processed data, the associated updated one or more pre-defined thresholds and set-points, and the energy management information by the energy transaction layer.

At block 112, energy of the multi customer distributed facilities is substantially simultaneously managed using the generated control commands by the energy transaction layer.

The asset management is explained with reference to screens 1800 and 1900 shown in FIGS. 18 and 19, respectively. The billing management is explained with reference to screen 2000 shown in FIG. 20. The invoicing and cost management is explained with reference to screen 2100 shown in FIG. 21. Further, performance, compliance and efficacy of the system are intelligently reported to the multi customer distributed facilities by the framework and utilities layer via the user interface layer. The performance of the system is explained with reference to screen 1200 shown in FIG. 12. The efficiency of the system is explained with reference to screen 1400 shown in FIG. 14.

Referring now to FIG. 2, which illustrates functional energy management architecture 200 for energy management of the multi customer distributed facilities located in different time zones, such as the one shown in FIG. 1, according to one embodiment. As shown in FIG. 2, the functional energy management architecture 200 includes a data acquisition/integration layer 202, a data management layer 204, an energy transaction layer 206, an energy efficiency management layer 208, a user interface layer 210, and a framework and utilities layer 212. Further, the data acquisition/integration layer 202 includes automated meter data 214, emissions data 216, digital invoice data 218, device and sensor data 220, ERP data 222, weather data 224, service desk data 226 and emergency alert data 278. Furthermore, the data management layer 204 includes a data validation module 228, a data normalization module 230, and a data mediation module 232. In addition, the energy transaction layer 206 includes an energy transaction processing module 234, a billing, invoicing and cost optimization engine 236, an event management module 238, and an asset operations and maintenance (O and M) module 240. Moreover, the energy efficiency management layer 208 includes a service management module 242, an energy efficiency management module 244, a configuration engine 246, and a customer energy knowledge base 248. Also, the user interface layer 210 includes a energy O and M module 250, an availability management module 252, a policy management module 254, a procurement management module 256, an invoice and billing module 258, a configuration management module 260, a project management module 262, a measurement and verification module 264, and an administration module 266. Further, the framework and utilities layer 212 includes a modeling engine 268, an energy knowledge base 270, a data aggregation module 272, an energy analytics and historical data storage module 274, and an energy reporting engine 276.

Furthermore, the data acquisition/integration layer 202 is communicatively coupled to the data management layer 204. In addition, the data management layer 204 is communicatively coupled to the energy transaction layer 206. Moreover, the energy transaction layer 206 is communicatively coupled to the energy efficiency management layer 208. Also, the energy efficiency management layer 208 is communicatively coupled to the user interface layer 210. Further, the framework and utilities layer 212 is communicatively coupled to the data acquisition/integration layer 202, the data management layer 204, the energy transaction layer 206, the energy efficiency management layer 208, and the user interface layer 210.

In operation, the modeling engine 268 in the framework and utilities layer 212 forms associated energy models of the multi customer distributed facilities based on parameters, such as facility characteristics, device characteristics, service characteristics, customer needs, available energy sources, customer policies, regulatory policies and the like using the user interface layer 210. Further, the data acquisition/integration layer 202 obtains data associated with energy management of the multi customer distributed facilities based on the formed associated energy models. For example, the data acquisition/integration layer 202 obtains automated meter data 214, emissions data 216, digital invoice data 218, device and sensor data 220, ERP data 222, weather data 224, service desk data 226 and emergency alert data 278 associated with energy management of the multi customer distributed facilities based on the formed associated energy models.

Furthermore, the data management layer 204 transforms the obtained data for energy management of the multi customer distributed facilities located in multi time zones. In one exemplary implementation, the data management layer 204 transforms the obtained data and enables data correlation for further processing. Further, the data management layer 204 encapsulates and abstracts the functional energy management architecture 200 from complexity of multiple protocols, data coming in various formats, unclean and incorrect data. In one embodiment, the data mediation module 232 mediates the obtained data. The data normalization module 230 then normalizes the mediated data. The data validation module 228 then validates the normalized data.

For example, the data mediation module 232 converts data format and naming from one set of protocols to another set of protocols to form a uniform logic, for example, from building automation control network (BacNET) to simple network management protocol user identities (SNMP UIDs). The data normalization module 230 normalizes the data for further processing as required. For example, the data normalization module 230 converts temperature data from deg f. to deg c. The data validation module 228 performs syntactical and semantic data validation on the obtained data. For example, the data validation module 228 can detect errors, such as Delhi temperature sensor showing −5 deg which is not a valid value.

In one embodiment, the data management layer 204 manages data associated with multiple meters and models the data for total consumption and service breakup consumption of MSAs. Further, the data management layer 204 automatically takes care of multiple meter issues like meter resets, meter data loss, meter data delay and the like and provides feedback regarding the issues on a real time basis. The data management layer 204 then corrects the data based on multiple estimation techniques. Particularly, the data management layer 204 provides consumption breakup with a granularity of hourly, daily and monthly levels that allows for calculation and segregation of consumption between services using asset status data instead of the meter data in a situation where a lower level of accuracy is acceptable.

In addition, the energy transaction layer 206 process the transformed data to obtain energy efficiency improvement features, such as consumption profiling by an operation mode, thermal profiling by service consumption, normalization of data obtained from multiple time zones, consumption data profiling by service type using virtual meters and model information and intelligent estimation techniques for missing consumption information, thermal profiling of SCAs, eco-mode profiling, savings estimation, asset utilization and capacity profiling, data validation based on customer and region characteristics, correlated validation, correlated data, device characteristic validation, industry, past performance, climate, policies, load conditions, and service for validation, device, area and service chain based event/ticket enrichment of dependent devices, services, areas (e.g., a SCA, a MSA, a site and the like) and the like. Particularly, the energy transaction processing engine 234 process the transformed data to obtain the energy efficiency improvement features.

In one embodiment, the energy transaction processing engine 234 provides a semantic value to real time energy performance and meter data corresponding to the associated model. Further, the energy transaction processing engine 234 calculates the consumption and various service quality parameter elements for various elements, such as the SCA, the MSA, a service, a meter and so on. Particularly, the energy transaction processing engine 234 calculates consumption at the level of the MSA, which is basically the aggregation of data over multiple set of meters, or an average temperature of a room (i.e., the SCA) covering a set of temperature sensors in the room, or the calculation of business load, which is the consumption value at a load consumption element (LCE), which consumes different service loads and generate useful business output. In some embodiments, the energy transaction processing engine 234 also applies various threshold evaluations, for multiple performance data types, and control backs in as required. For example, of the control, is the optimization of economizer threshold based on current weather conditions.

For example, the billing, invoicing and cost optimization engine 236 handles data related to utility service consumption, like billing, invoice, and cost associated with the consumption of the service. The billing, invoicing and cost optimization engine 236 includes multiple business logics related to utility data handling, such as notification for bill due dates, reporting for highest cost/day, bill overdue statistics, statistic regarding wrong bills like overlapping bills, incorrect bill data and so on. In some embodiments, the billing, invoicing and cost optimization engine 236 also performs carbon emission and calculation on top of utility data by taking care of multiple regions, suppliers and the like. In one embodiment, billing, invoicing and cost optimization engine 236 also encapsulates the logic of sub tenant billing.

Further, the event management module 238 handles event management functions, such as event de-duplication, event enrichment, event co-relation, event acknowledgement, event cancellation and the like. The event management module 238 reduces the number of events handled by upper layers and support user actions via an acknowledgment and a cancellation. Furthermore, the asset O and M management 240 handles standard asset management functions, such as asset lifecycle management using preventive, predictive maintenance, use of job plans, workforce management related to job plans and the like.

In addition, the energy efficiency management module 244 runs various intelligence and custom coded business logics, which use the data available at various model elements (i.e., the energy efficiency management module 244 checks at an average how much an SCA as overcooled/under cooled by checking the data over a month and comparing with appropriate thresholds). Also, the service management module 242 performs standard service management functions, such as problem and ticket management, service level agreement (SLA) management associated with the problems and tickets, manpower and efficiency management for handling these problem and tickets and policy compliance management. In one embodiment, the customer policies and regulatory policies are inputted in to the energy efficiency management module 208 by the user interface layer 210. The policy management is explained with reference to a screen 900 shown in FIG. 9.

Moreover, the configuration engine 246 handles the end user configuration and provides a user interface (UI) and automatic upload interfaces for the configuration of the entire platform. The configuration can be enterprise data, such as a configuration of an enterprise like organization hierarchy, an asset configuration such as, model and vendor, model and asset relationship like SCA, MSAs and so on, utility related information like utility suppliers and so on. The configuration engine 246 handles the complete configuration of the functional energy management architecture 200.

Further, the customer energy knowledgebase 248 includes a copy of customer applicable knowledge in form of data, such as inefficient temperature ranges and the like. The data is copied at the start of customer provisioning in the energy knowledge base 270.

In one embodiment, the energy efficiency management module 244 performs thermal profiling and derives combined temporal and spatial thermal profile characteristics of a SCA on a continuous basis by tracking changes in the profile. The energy efficiency management module 244 performs thermal profiling which is independent of the SCA's provisioned and time zones of the SCA. The energy efficiency management module 244 performs thermal profiling on thermal and asset status data by segregating and relating the data based on the service model and time zone information and then combines the profiles of the spatial and temporal distribution of the data. The energy efficiency management module 244 then compares the profile with knowledge base thresholds and raise exceptions in case if the profile crosses the thresholds.

In one embodiment, the energy efficiency management module 244 automatically rectifies the profile. In another embodiment, the energy efficiency management module 244 provides the energy management information for rectification of the profile to the energy transaction processing engine 234. The inputs to the energy efficiency management module 244 for thermal profiling include time series temperature data from the sensors and status data of assets responsible for maintaining thermal condition, service relationship between the target SCA and the assets responsible for maintaining thermal condition, policies for SCAs, and threshold percentages. The outputs of the energy efficiency management module 244 for thermal profiling include overcooling/heating and under cooling/heating % of the SCA with a granularity of day and aggregated to month, non uniformity of thermal profile in percentage, subareas in the SCA with thermal problems, subareas in the SCA which are in deviation with an average profile, deviations with policies, and auto correction of profile if possible.

Further, the energy efficiency management module 244 performs consumption profiling, by operation modes, by segregating the consumption of a MSA based on the different operation modes. The energy efficiency management module 244 then compares the different operation modes and provides information regarding normal consumption for non-core hours (for example, partial service after business hours) in comparison to the core hours (full service business hours). The profile tracking is done on a continuous basis with a granularity of daily, weekly and monthly. The energy efficiency management module 244 works independently of the MSA's provisioned and the time zones of the MSAs. The energy efficiency management module 244 works on the consumption and MSA state data (i.e., data which indicates at what mode the MSA is operational), segregates and relates based on the service model and time zone information and then compares the profile between the different MSA states.

The energy efficiency management module 244 then compares the profile with knowledge base thresholds and raise exceptions in case if the profile crosses the thresholds. Exemplary operation modes are normal mode of operation (i.e., business hours which are customer hours in a store or normal office time in an office area), partial service hours (i.e., an employee only hours in the store when full service and lighting are not required. After the store is closed down the period is referred to as afterhours i.e., OFF mode of operation when except for few essential services like power for a server etc., everything else is supposed to be shutdown). There is also possibility of reduced mode of operation i.e., demand limit hours during the business hours due to other considerations like lean business period, high tariff, demand limit tie up and so on. After profiling the consumption for each of this period, the rule detects the above normal consumption for each of the periods as compared to the normal mode period for the MSA. The daily average consumption for each period is compared with the normal hour's consumption and above normal consumption is detected. The analysis helps in the detection of loads that remain ON during afterhours because of improper operation and policies, which needs to be optimized.

Furthermore, the energy efficiency management module 244 performs eco-mode profiling. The eco-modes are different operation modes in which a site can operate using free ambient resources for the major service groups like lighting resulting in reduction of consumption from the utilities. The energy efficiency management module 244 determines potential of utilizing eco-modes (e.g., hours in eco-mode) by and collecting weather data 224 from provided weather feeds on a periodic basis. The energy efficiency management module 244 then compares the hours in eco-mode with the hours the site in eco-mode and generates a profile and raises an exception if the profile crosses the knowledgebase thresholds. The energy efficiency management module 244 also compares whether the assets providing the co-respective service group is utilizing the eco-mode to provide the service. The energy efficiency management module 244 uses the asset status data to find the eco-mode utilization, generates a profile of utilization and then raises an exception if the profile crosses the knowledgebase thresholds. In some embodiments, the energy efficiency management module 244 corrects the profile by calibrating the usage of eco-mode on a dynamic basis. The profile tracking is done on a continuous basis with a granularity of daily, weekly and monthly. The energy efficiency management module 244 works independent of a number of sites provisioned and time zones of the sites.

In addition, the energy efficiency management module 244 performs utilization profiling based on assets status data of assets. The energy efficiency management module 244 takes into account the redundancy of capacity required and arrives at the thresholds for high or low utilization. The energy efficiency management module 244 raises an exception which leads to information for changing the active and redundant capacity configuration so that improvement of utilization can be brought about resulting in improvement of efficiency, if there is a threshold violation.
